EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 756,312, dated April 5,1904.

Application filed August 29, 1903.

To all whom it may concern:

Be it known that I, LEO F. AM, of Troy, in the county of Rensselaer andState of New York, have invented certain new and useful Improvements inEyeglasses; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention relates to improvements in eyeglasses, and has forits object-to provide an. improved connection for securing the springand guards to the lenses in such a manner as to eliminate thepossibility of relative motion of the parts and consequent loosening ofthe screw and to provide a device of this character that may be employeduniversally with springs and guards having both horizontally andvertically extending attaching portions.

To these and other ends my invention consists in certain features ofnovelty to be hereinafter more fully described, and pointed out in theclaims hereunto annexed.

In the drawings, Figure 1 is a perspective view of a portion of aneyeglass having one form of my invention applied thereto. Fig. 2 is adetail view of the blank from which a portion of the attachment isformed. Figs. 3 and 4: are views of an attachment and blank embodying amodified form of my invention. Figs. 5 and 8 are perspective views ofmodifications of the above-described forms, and Figs. 6 and 7 are viewsof another modified form of attachment and the blank thereof.

The same numerals of reference designate similar parts in the severalviews.

In the several embodiments of my invention as herein shown an ordinaryform of lens-attaching post or stud is employed in connection with myinvention, such stud or post comprising a shank or body portion 1,formed in any suitable manner and provided with a clip having the shoes2 2 thereon toengage the edge of a lens and one or more lugs or ears 33, arranged to engage upon the sides of the lens and perforated toreceive a fastening-screw 4. To the opposite end of a post or studformed in the above or any de- Serial No. 171,280. (No model.)

sired manner is attached a box wherein the attaching ends of the springand the guard-arms are secured, and in the embodiment shown in Figs. 1and 2 a blank 5, substantially L-shaped, is punched or otherwise formed,preferably, from sheet material, the ends 5 5 thereof being folded orbent back in opposite directions to form the seats 6 7, arranged atright angles to each other upon opposite sides of the interveningpartition 5, separating them. Into these seats or apertures 6 7 thusformed are adapted to be inserted the attaching arms or portions of thespring 8 and the guard 9, respectively, said seats being so formed andarranged as to receive the attaching portions of springs and guards ofany ordinary type or construction, wherein said portions may extendhorizontally on the spring and vertically on the guard, or vice versa.The box thus formed may be soldered or otherwise secured to the bodyportion 1 of the post and is apertured to receive a screw 10, adapted toperforate the attaching ends of the spring and guard to securely lockthem in position.

In Fig. 3 is illustrated a box formed in a somewhat different manner, aT-shaped blank 11 having the laterally-disposed arms 11 11", adapted tobe folded back of the portion v11 of the blank, and an arm 11, adaptedto be folded in the opposite direction to form a box having the seats 1213 arranged at right angles upon each side of the intervening partition11". That side of the box thus formed having the abutting ends of thearms 11 11 is preferably soldered or otherwise secured to the bodyportion of the post, said box being perforated to receive thefastening-screw, the head of which will bear upon the portion 11 of thebox to compress it, and thereby securely clamp the spring and guard armsat, right angles in relation to each other and within the box uponopposite sides of the partition 11.

In Figs. 5 and 8 a box is illustrated that may be formed of a straightstrip of sheet material, the form shown in Fig. 6 being made by foldingthe extremities of the strip back upon opposite sides of the centralportion thereof to form a box having the seats l t 15 arranged atopposite sides of the intervening partition 16. In Fig. 8 the box issimilarly formed; but instead of the central portion of the blankforming the partition the end 17 guard and spring arms extend in thesame or parallel directions, said boxes being suitably mounted upon thebody of the post and perforated to receive the clamping-screw forcompressing said box and securely holding the attaching portions of thespring and guard in position.

The form illustrated in Fig. 6 is adapted to be made from a blanksimilar to that shown in Fig. 7, having the oppositely disposed flanges2O 20 adapted to be bent or turned perpendicularly to the surface of theblank and the arms 21 21 adapted to be folded in an opposite direction,the parallel flanges 20 20 forming a channel or seat between them uponone side and the folded arms 21 21 a seat arranged at right anglesthereto at the opposite side of the intervening partition 22, the boxthus formed being suitably secured to the post or stud with, preferably,the flanges 20 20 free orextending outwardly. The box and body of thestud may be perforated to receive a fastening-screw the head of whichwill bear upon the spring or guard arm interposed between said flanges20 20 to clamp the same in position and to compress the interveningportion upon the attaching portion uponthe opposite side thereof, andthereby firmly secure said attaching portion in position.

In the various embodiments herein shown it will be obvious that a box isprovided that may be readily and cheaply produced and suitably securedto any ordinary form of attaching post or clip, wherein a compressibleor yielding action of the material comprising the box is secured,enabling the clamping or fastening screw to firmly and positively holdthe spring and guards in their proper positions, and the" reactionaryeffect of the compression will exert a constant pressure against thescrew head to produce a friction tending to resist theloosening of thescrew. However, all possibility of the loosening of the screw andrelative motion of the parts is practically eliminated by arranging thescrew to bear upon a stationary portion of the box and clamping theattaching portions of the spring and guards at opposite sides of anintervening stationary portion of the box and so forming the seatstherein as to provide portions bearing against both lateral edges of theparts to be clamped to prevent edgewise movement thereof.

I claim as my invention- 1. A device of the character described,comprising a portion adapted to be attached to a lens, a box thereonhaving seats therein adapted to receive the ends of thesp'ring and guardarms, and a partition in said box between said seats.

2. A device of the character described, comprising a body portionadapted to be attached to the lens. a box formed of sheet material andattached thereto having seats formed therein to receive the attachingportions of the spring and guard, and having a partition between saidseats, and a screw for clamping said attaching portions within said box.

3. A device of the character described, comprising a body portionadapted to be attached to a lens, and a compressible box carriedthereby, having seats formed therein to receive the ends of the springand guard arms, a partition formed in said box between said seats, and aclamping-screw having a portion adapted to bear upon a portion of saidbox to clamp said attaching ends therein.

4. In a device of the character described, the combination with a bodyportion adapted to be attached to a lens, of a box formed of an integralpiece and secured thereto having seats formed therein to receivethe'attaching ends of the spring and guards, a partition formedintegrally with said box between said seats upon opposite sides of whichsaid attaching ends are adapted to bear, and a screw for clamping saidends within said box.

5. In a device of the character described, the combination with theshank or body portion having devices thereon to engage a lens, of a boxformed integrally of fiat material having its ends bent or folded inopposite directionsto form seats arranged upon opposite sides of anintervening portion to receive the attaching ends of the spring andguards, and a screw passing through apertures in said box and saidspring and guard ends, and having a portion adapted to bear upon aportion of said box to compress it and clamp said attaching endstherein.

6. The combination with the shank or body portion of a stud or post andlens-attaching devices carried thereby, of a box formed of a blank ofsheet material having oppositely-disposed portions thereon adapted to befolded upon opposite sides of an intervening portion thereof to formseats arranged at opposite sides of a partition to receive the attachingends of the'spring and guard, the box thus taching ends of the springand guards, and having its free end located at one side thereof topermit a yielding action between said yield- I5 able and attachedportions,the box thus formed being apertured to receive afastening-screw adapted to produce a compression between said portions.
